I wish I could make it better, @sumterescapes.
As much as I'd love to offer help and cancel your subscription, we've got a separate team who can identify why you received an error message and get rid of it.
With this, I'd recommend contacting our Customer Care Support directly from the Help menu. Let me show you how.
- Go to Help.
- Select Contact Us.
- Enter Cancel Subscription in the What can we help you with? field.
- Click Continue.
- Chose a channel where you want to connect with our specialists.
With their tools, one of our specialists can work with you and completely cancel your subscription.
On top of that, I've also included this reference for a compilation of articles you can use while working with us: What happens to my QuickBooks Online data after I cancel?
If there's anything else that I can help you with, please let me know in the comments. I'll be here to lend a hand.
